Subject: [OMPI devel] Libevent update

Hi all

As mentioned on the telecons and in prior mails, I have been working on updating the event library to libevent 2.0. While doing so, I have significantly simplified the integration so that we can perform such updates much quicker/easier in the future. Basically, it now requires simply unpacking the tarball and modifying two files to include a line or two.

Because of the integration change, it is possible that some things were missed. Therefore, it would be a REALLY GOOD IDEA for people to test my Mercurial branch before I bring this stuff over to the trunk.

See the branch at http:/

I know we have a bad history of people not doing such testing, but I'm asking you to make a special effort here. Otherwise, you really don't have a good reason to complain later. :-)

This update retains all the prior behaviors - it just puts libevent 2.0 as the engine. Soon after this has soaked a little, we will begin implementing the advanced features available in this update. Specifically, we will create separate event bases for the MPI and ORTE layers, thus allowing us to progress those layers independent of each other.

I will continue to do some work on the branch (cleanups, remove opal_progress_thread stuff since it doesn't work anyway), but will ensure that the branch always works for those of you testing it. Barring any reported problems, I will check this into the trunk in about a week.
